While the cutter rotates in a circle around the valve seat, a feed gear mechanism ensures a continuous outward transverse feed motion under the proper seat angle. This angle is defined by an inclined slideway provided for the tool slide in the exchangable adapter head.
The lathe-type refacing action provides a flawless concentric seating surface texture for a complete valve seal.
Features:
The machine is fitted with two motors providing a smooth cutting action. The speed of the motors is infinitely variable so that the circular motion of the cutter around the valve seat can be adapted to the diameter and material of the valve seat.
The motors are of the low voltage type to eliminate electric hazards. The control circuits are housed in a separate power supply unit to reduce the weight of the machine for ease of handling. The exchangeable adapter head with the built-in slideway for cutter travel ensures a precise seat angle.
Roundness, concentricity and surface finish of the refaced valve seat are within manufacturers specifications or even better.
The machine has been tested and approved by the leading engine manufacturers.
Handling:
Setup is fast and easy.
First, lock the pilot with mounted centering spider in the valve guide. Then, lower the machine over the pilot and position the cutter in front of the inner edge of the valve seat. Turn micrometer downfeed to set the desired depth of cut.
Refacing is automatic.
Pressing one button is enough to start both the rotation and the transverse feed of the cutter.
